Title: Noise reduction circuit
Inventor: ASANO MITSUYASU
IPC: H04N5/21
Filed: 1987-05-08
Abstract: PURPOSE:To reduce noise of a video signal without using a memory of large capacity and without losing the precision by detecting a field difference or frame difference as to a signal of a high frequency component having a prescribed amplitude or below including noise. CONSTITUTION:An input signal S1 including noise is fed to an adder 3 via an LPF 12 and fed to an HPF 10. The output of the HPF 10 is fed to an adder 2 and an A/D converter 4 as a signal including noise via a limiter 11, the converted output becomes a signal retarded by one field via a field memory 5 and a D/A converter 6 and the result is fed to the adder 2. When the addition output is not zero, noise component is obtained, the difference signal is multiplied by a multiple of K at a multiplier 8 and fed to the adder 3. As a result, the output signal whose noise is reduced is obtained.

Title: Releasable tape system and pressure-sensitive adhesive tape prepared by using the same
Inventor: ARAKAWA MASAAKI
IPC: C09J7/02
Filed: 1992-04-03
Abstract: PURPOSE:To obtain a pressure-sensitive adhesive tape which does not increase its adhesiveness to a polyolefin adherend at a released part with time by using an acrylic pressure-sensitive adhesive as its pressure-sensitive adhesive layer and specifying the holding time under load and the adhesive strength under shear. CONSTITUTION:This releasable tape system is one which can be released at the interface between the polyolefin adherend and the pressuresensitive adhesive tape. The pressure-sensitive adhesive layer comprises an acrylic pressure- sensitive adhesive and has a holding time of 10min or above under a load of 1kg and an adhesive strength under shear of 0.5kg/25mm or above, and the force of release of the pressure-sensitive adhesive tape from the adherend is 1000g/25mm or above. This system is featured in that a member such as a tape is difficultly separable in fixing while it is easily peelable. Therefore it is useful for forming a releasable part of, e.g. a paper diaper, a structure of a releasable part of a disposable absorptive article or a medical tape and for opening and shutting a package for an article.

Then, nitrogen gas is fed to the bellows 3 and 7 respectively, and the pressure is regulated to make the fastening surface pressure of the stack in a specific value. As the height of the stack is contracted during the baking, the height of the bellows 3 and 7 are extended and the fastening force in the baking can be maintained constant. After the baking operation is over, the interval between the fastening plate 4 and an upper fastening plate 5 is regulated to make the bellows 3 in the contracted condition by fastening bolts 6 for operation, and the bolts 6 are fixed. And after that, the gas pressure is released only from the bellows 7, and the bellows 7, the fastening plate 8, and the bolts 9 are removed.

Title: Clock with accessory mechanism
Inventor: WATANABE ISATO
IPC: G04C3/14
Filed: 1981-07-17
Abstract: PURPOSE:To make it possible to use a battery effectively by shutting off an oscillation circuit and frequency divider circuit and other circuits from the battery at starting an accessory mechanism that requires a large starting current and supplying them condenser current. CONSTITUTION:When output is generated from a drive circuit DR2 at a desired time, a switch S is controlled through a timer circuit TM during the timer period so as to shut off a dribe circuit DR1 and other circuits that include a clock pulse generator CL, a frequency divider circuit, etc. from a power source battery E, and those circuits operate normally by the discharge current of a condenser C. Diring the timer period of a certain length a transistor T is turned ON through the circuit DR2, and accessory mechanism of a motor M2 and so on that require a large starting current are supplied a large current from the battery E. Voltage drop in the battery E due to this curent has no effect on the generator CL, the circuit DR1, etc. Accordingly, if the shut-off of the switch S is restored after the timer period is passed, whereupon the accessory mechanism becomes stable and the mormal voltage is left in the battery, the battery E has not to be replaced; it can be used continuously with the result of effective use of battery.

IPC: G01S3/803
Filed: 1990-04-27
Abstract: PURPOSE:To enable a direction of arrival of a passive sound in water to be detected accurately and automatically by calculating an orientation based on a level ratio at which a same signal appears in a plurality of beams and directivity pattern of a beam for each frequency. CONSTITUTION:A microphone in water receives signal, performs phasing, forms a beam, performs frequency analysis of signals 200 - 236 arriving at each terminal 100 - 136, selects a plurality of possible beams in the orientation of arriving sound in water based on the result, and then selects 1 frequency constituents of each beam which indicates a maximum level. Then, directivity pattern is memorized for each frequency at a beam pattern memory part 3. An orientation part 2 inputs directivity pattern corresponding to each beam which is selected 1 from this memory part 3 and then automatically calculates orientation of arriving sound highly accurately from a level ratio of this pattern and spectrum with high frequency analysis value of each beam.

Abstract: PURPOSE:To make it possible to safely and simply measure the charging voltage at the terminal part of a power cable, by detecting the voltage between the suspended electrode wound around the rain protecting part provided to the terminal part of the power cable and a cable shielding electrode by a light/voltage sensor. CONSTITUTION:A power cable 1 has such a structure that the insulating material 3 exposed from an external shielding electrode 2 is covered with a rain protecting member 4 and a terminal part connection metal fitting 6 is attached to the conductor 5 led out from the insulating material 3. At the time of measurement, the outer periphery of a conductive or semiconductive member 7 is covered with an insulator 8 to form a suspended electrode 9 which is, in turn, wound around and attached to the outer periphery of the rain protecting member 4 between walls 4a and the leading end of a lead wire 10 is connected to the semiconductive member 7 of the suspended electrode 9. At this time, because the charging voltage of the power cable 1 is divided between the lead wires 10, 14 connected to the suspended electrode 9 and a shielding electrode 2, this voltage is converted to light by a light/voltage sensor 15 while the light is transmitted to a light/voltage meter 17 by an optical fiber 16 to make it possible to display voltage.
